SPECIFICATION forming part of Letters Patent No.329,896, dated November10, 1885. Application filed July 22, 1885. Serial No. 172,344. (Nomodel.)

To all whom it may concern.-

Be it known that I, JOHN J. FLOYD, of Boston, in the county of Suffolkand State of Massachusetts, have invented an Improvement in PrintersGage-Clamps, of which the following is a specification.

The object of my invention is to provide a cheap, simple, and convenientspring gageclamp for tympan-sheets of j ob-printing presses, adapted tobe connected with and adjusted upon the tympan-sheet of the platen, ashereinafter set forth; and it consists in the novel construction of theclamp device hereinafter more fully described and set forth in theclaim.

Figure 1 represents a perspective view of my invention secured to apiece of platen-pa per in position for use. Fig. 2 represents a verticallongitudinal section of the same. Fig. 3 represents a sectional endelevation of the same.

A represents a flat sheet-metal spring-clamp, being bent aboutmid-length so as to form two main parallel portions. The under one, B,is provided at about mid-length with a short screw bolt or stud, O,which extends upward through an opening or hole formed in the upperportion, D, and is provided with a thumbnut, E, as shown. The said upperportion,

D, is turned upward at the front end, so as to form a vertical stop orgage, F, from the lower portion of which project two points, H,which areadapted to be forced into the platen-sheet or tympan-sheet when saidlower portion, B,

is inserted through a slit cut in the platen- 35 sheet at the desiredpoint, as shown in Fig. 1, and the said thumb-nut is turned so as todraw the said portions B and D toward each other, so as to firmly gripthe portion of tympan sheet between said portions, and thus 0 secure theclamp thereon in the position desired to form a gage to feed the card orother paper against when being printed in the usual manner, asheretofore. Now, in order to guide the edge of the card or other paperbeing 5 printed into position against the said gage F,

I provide an adjustable finger piece, L, which is secured at its rearend upon said bolt and nut, and resting upon the top of the upperportion, D, as shown, its forward end being 0 bent or curved upward andprojecting beyond said gage or stop portion F, as shown.

I am aware that gage-pins have heretofore been employed for asimilarpurpose. Therefore I do not claim such as my invention.

Having thus described my invention, what I claim is The above describedspring gage clamp, consisting of the spring portion A, parallel clampportions B and D, provided with a 60 screw-bolt, O, and nut E, andhaving the stop or gage F, and provided with the adjustable finger-pieceL, as shown and described.
